[SOLVED] Firefox creates CPU spikes

Whenever I have firefox running, it will spike one of the cpu cores at regular intervals.
The culprit is one of its child processes called "RDD Content".
Does anyone else get this behavior or know if it's normal?

I answered my own question.
It's a sandbox process called Remote Data Decoding and it does have a reputation of being greedy with cycles.
Any media being played gets funnelled through the RDD process.
I went to about:config and enabled the advanced media.rdd settings for all the supported codecs and it cut the cpu usage by two thirds.
